Rock gardens use rocks and stones to help anchor the garden to its location. Ground covers and flowers are planted between the rocks. These types of gardens can use locations that other types of gardens have problems with, such as slopes and grades. Rock gardens generally have poor soil qualities and dry conditions. - The yellow sulfur flower (Eriogonum umbellatum) is an evergreen, perennial flower that grows up to a foot tall.
